(o1. 28%25) My inventionrelates to unions for connecting and forms a tight joint in conjunction thererange boilers or hot watertanks to the water with, the parts beingheld in'positi'o'ri by gravity supply pipes, and its principal object is to preonly so that an excess of pressure within the tank vent siphoning of the boiler or tank when the will'cause the pipe 15 and the flange l6 tobe lifted 5 stop and waste in the supply pipe is shut off. upwards, therebyreleasin'g the pressure.
